How Propel Helped Fertitude Launch a Seamless Period Tracking Feature

Background

Fertitude, a leading digital health platform specialising in women’s reproductive health, sought to expand its app’s capabilities with the introduction of new period tracker features. As part of their International Women’s Month initiative, they aimed to offer a more intuitive and accurate cycle-tracking experience for their users, necessitating thorough, targeted, and insights-driven user testing to guarantee a seamless experience.

Fertitude faced the challenge of validating their new period tracker features before rolling them out to the public. Their primary concerns included:

  • Assessing the robustness and usability of the new features.
  • Ensuring seamless and intuitive user experience.
  • Gathering comprehensive user feedback to refine the experience.
  • Finding a diverse and engaged group of 100-120 female testers.
  • Conducting an efficient and structured testing phase without disrupting their existing operations.

Without a reliable partner to facilitate user recruitment and testing, Fertitude risked launching a feature that might not fully meet their audience’s needs.

Leveraging Propel's 'Community as a Service' offering

Fertitude partnered with Propel to efficiently recruit and manage a high-quality pool of female testers. Through this collaboration, Propel:

  • Curated a pool of 120 engaged female app testers from its extensive network, representing different demographics and user personas, to precisely match Fertitude's required demographic.
  • Facilitated structured usability testing, providing testers with a framework to assess the feature’s accuracy, ease of use, and functionality.
  • Streamlined feedback collection, using a combination of surveys, direct interviews, and real-time analytics to capture actionable insights.
  • Offered strategic recommendations, ensuring Fertitude’s team could refine the features based on user experiences and insights before the official launch.

By leveraging Propel, Fertitude was able to focus on enhancing the app while we handled the complexity of user recruitment and testing logistics.

Key Outcomes Challenges:

  • 92% tester engagement rate, with nearly all participants completing the full testing cycle.
  • Over 500 detailed user insights received, providing a comprehensive understanding of the app’s functionality and user experience.
  • 17 critical UX enhancements implemented, refining navigation, accessibility, and feature clarity.
  • Reduced development cycle by three weeks, accelerating time to market.
  • Increased user adoption rate by 40% post-launch, surpassing initial projections.
  • Higher retention rates, with more users consistently engaging with the period tracker feature after launch.

With Propel, Fertitude turned a critical pre-launch challenge into an opportunity to refine its product and deliver exceptional value to its users.

Propel’s ability to rapidly recruit and manage high-quality testers saved us weeks of development time and gave us the confidence to launch, knowing the features had been rigorously tested by our exact target user.
